It would be D.

Step-by-step explanation:

This formula, A=1/2 bh, 1/2 base multiplied by height, is used to find the area of a triangle, therefore, D is the only viable answer.

Answer:

Average speed = $\frac{(x+y)}{2}$ miles per hour

Step-by-step explanation:

Formula to calculate the average speed of an object is,

Average speed = $\frac{\text{Total distance covered}}{\text{Time taken to cover this distance}}$

If I travel with the speed of x mph for t hours,

Total distance covered = Speed × Time

= $x\times t$

= $xt$ miles

Similarly, if I travel with the speed y mph for t hours,

Total distance covered = $yt$ miles

Total distance covered by me = $(xt+yt)$ miles

Total time taken to cover this distance = $t+t$

= $2t$ hours

Therefore, expression for the average speed will be,

Average speed = $\frac{xt+yt}{2t}$

= $\frac{(x+y)t}{2t}$

= $\frac{x+y}{2}$ miles per hour

Name the binomial you can multiply by (x + 9) to get the product x^2 + 5x- 36

SpyIntel [72]

If you would like to solve (x^2 + 5x - 36) / (x + 9), you can do this using the following steps:

a = ?
(x + 9) * (x + a) = <span>(x^2 + 5x - 36)
x^2 + ax + 9x + 9a = x^2 + 5x - 36
ax + 9x = 5x
a + 9 = 5
a = 5 - 9
a = - 4

The correct result would be x - 4.

Please help me with this math problem!! :)

Step-by-step explanation:

the following things are clear : opposite sides are of equal length, the sum of all angles in a square, rectangle or general parallelogram is 360 degrees, and opposite angles are equal.

so,

y² + 7 = 32

y² = 25

y = 5

2y² = k

2×5² = k

50 = k

the opposite angle of 150 is also 150 degrees.

the opposite angle of x is also x.

so, we have as sum of angles

360 = 150 + 150 + x + x = 300 + 2x

60 = 2x

x = 30 degrees

17-7 (x-3) + x = 86 equations w/ distributing and variables on both sides

Over [174]

$17-7(x-3)+x=86\\\\
17-7x+21+x=86\\\\
38-6x=86\ \ \ \ |Subtract\ 38\\\\
-6x=48\ \ \ |Divide\ by\ -6\\\\
x=-8\\\\ Solution\ is\ x=-8.$
